(ci. 12s- 87) 1 Claim. 1

The present invention relates to new and useful:

improvements in surgical splints,.and has for its primary object toprovide, in a manner as hereinafter set forth, an appliance of thischaracter which is adapted to be expeditiously and accurately adjustedto meet various conditions. l Another very important object of theinvention is to provide an adjustable surgical splint of theaforementioned character comprising novel traction means.

Other objects of the invention are to provide a surgical splint of thecharacter described which will be comparatively simple in construction,strong, durable, highly efficient and reliable in use, compact, light inweight, and which may be manufactured at low cost. Y All of theforegoing and still further ,objects i and advantages of the inventionwill become apparent from a study of the following specification, takenin connection with the accompanying drawing wherein like characters ofreference designate corresponding parts throughout the several views,and wherein:

Figure 1 is a top plan view of a back splint constructed in accordancewith the present inven- Figure 2 is a cross sectional view, taken subjstanuauy on the une 2-2 of Figure 1.

Figure 3v is a bottom plan view of one of the cross members of the backsplint with an endf portion thereof broken away.

Figure 4 is a top plan view of an arm splint assembly.

Figure 5 is a view in side elevation of the arm splint.

Figure 6 is a bottom plan view of the angularly adjustable member of thearm splint.

Figure 7 is a cross sectional view, taken substantially on the line 1-1of Figure 4.

Figure 8 is a top plan view, showing the traction device mounted on thesplint, with a portion thereof in section.

Figure 9 is a view in side elevation thereof.

Figure 10 is a cross sectional view, taken substantially on the lineIIJ- I of Figure 8.

Referring now to the drawing in detail, and to Figures 1, 2 and 3thereof in particular, it will be seen that reference numeral Idesignates generally a pair of spaced, parallel, longitudinallyeXtensible members of suitable material. The members I includetelescopic male and female sections 2 and 3, respectively. As best seenin Figure 2 of the drawing, the female sections 3 comprise side walls 4having inturned marginal flanges constituting guides for the malesections 2, said male sections being inthe form of flat bars.

The members I are rigidly but adjustably and detachably secured togetherin spacedparallelism by means including a plurality of cross bars 6. Themale and female sections 2 and 3 have formed longitudinally thereinparallel `series of openings 1 which are adapted to be' brought 'intoregistry. Bolts 8 areV engageable in the registering openings 'l'forsecuring the male and female sections 2 and 3 in adjusted position. Thebolts 8 are provided with wing nuts 9. The cross bars 6 are alsoprovided with openings IIJV which are adapted to be brought selectivelyinto registry with the openings 1.' The intermediate cross bar 6 issecured in position on the members I by the same bolts which connect themale and female sections 2 and 3.' Additional bolts are provided forsecuring the other cross bars 6 in position. The lower faces of thecross bars (i` are recessed, as at II, to accommodate the wing nuts v9.Handles I2 are provided on the ends of the cross vbars 6.

It will thus be seen that a back splint has been provided which may beexpeditiously assembled, adjusted as desired, and disassembled. Forother purposes than that of a back splint, but one of the members I maybe used with or without the cross bars 6 or,l if desired, either ofthemale of female sections 2 or 3 may be used alone.

' arrangementv of the openings: 1 and I0 is such asto permit virtuallyany desired adjustment to be expeditiouslyrhad. f

In Figures 4, 5 and 6 of the drawing, lreference character I3 designatesgenerally an adjustable splint which is primarily for use on an arm. Thesplint I3 comprises a female member I4, the major portion of which issubstantially similar in cross sectional shape to the sections 3. At oneend, the female member I4 terminates in spaced, opposed upper and lowerplates I5 having openings I6 in their longitudinal marginal portions.The other end portion of the female member I4 slidably receives forlongitudinal adjustment a male member I1. The male member I1 has formedtherein parallel series of spaced open-V ings I 8 for the reception of apair of securing bolts I9 in the adjacent end portion of the femalemember I4.

The plates I5 receive therebetween an angullarly projecting arm 20. Thearm 20 has formed in its inner end portion a multiplicity of openings 2Iwhich are to be brought into registry with Thel jtiaIlychannel-shaped ate mounted' Idritlie Ich "eef-eerselefeeeuni as to permit substantiallyAany angularity of said arm 2D relative to the female member I4. Bolts22 secure the arm 20 in adjusted position on the 'female member i4. Theopenings I G in both of the longitudinal marginal portions off theplates i5 permit the arm 20 to be reversed when the splint I3 is to beapplied to right or left arms.

The outer portion of the arm 20 is substantially similar in.crosssectional. ehape` tothe .fel male members andeiis*adapted'ftoslidably receive a male member 23 in the form of anextension. The extension 23 has` formed therein?! longitudinal series ofopenings 24 in Whichvbolts 25 in the outer portion of the arm 20 areselec` Y tively insertible for securing said extensin in adjustedposition.

The splint I3, after thedesi'red'- assemblyand' adjustments have beenmade, is to be ,appliedto the arm or other member in the usual'nan'nr.
